Description
Technical field
The present invention relates to a kind of anchor clamps, particularly a kind of bend pipe weld jig that is used to weld helical tube panel and bend pipe.
Background technology
Along with human industrial expansion, the demands for energy problem becomes increasingly conspicuous, and as the capital equipment of the heating power energy, people increase the performance requirement of boiler day by day.Wherein, the use of heat transmission equipment is also frequent day by day.
For example, in the 1000MW ultra-supercritical boiler, the water-cooling wall all around bend pipe of wall helical tube panel junction need weld with the pipe end of tube panel.Because the features of shape of bend pipe, the face and the tube panel at bend pipe place have one ≠ 90 ° angle, and this makes that bend pipe is difficult to splice with tube panel, and this makes troubles with regard to the welding sequence of giving the back.
Those skilled in the art is devoted to develop a kind of bend pipe weld jig, thereby the tube and tube screen that will loose is fixing accurately by designing requirement.
Summary of the invention
The technical problem that the present invention will solve is in order to overcome in the prior art, is difficult to fix when bend pipe and tube panel splicing, and ineffective deficiency provides a kind of novel bend pipe weld jig.
The present invention solves above-mentioned technical problem through following technical proposals:
A kind of bend pipe weld jig, its characteristics are that said anchor clamps comprise:
One substrate, secured in parallel is provided with a plurality of comb plate, comb joints on the said substrate;
One location-plate that is fixedly connected with said substrate is provided with an arc stopper slot and a gripper shoe on the said location-plate;
Wherein, when the straight section of bend pipe was placed on the comb plate, comb joint on the said substrate, the bending section of said bend pipe received the support of location-plate upper backup pad.
Preferably, an end of said gripper shoe rotatably is fixed on the said location-plate, and the rotating shaft of said end and the straight section of said bend pipe are on the straight line.
Preferably, the screw bolt and nut that is used for fixing said gripper shoe position is set in the said arc stopper slot.
Preferably, the rotating shaft place of said end is provided with a dial, and the angle of said gripper shoe rotation is corresponding with the scale on the said dial.
Preferably, said substrate is fixedly connected through a C clamp with a helical tube panel.
Preferably, said substrate is fixedly connected through an interior plug that expands with a helical tube panel.
Among the present invention, but above-mentioned optimum condition combination in any on the basis that meets this area general knowledge promptly gets each preferred embodiment of the present invention.
Positive progressive effect of the present invention is: this bend pipe weld jig is simple in structure, and is easy to operate, and fixing at any angle applicable to bend pipe and tube panel, applicability is wide, and the bend pipe of any specification all can be located.
Description of drawings
Fig. 1 is the structural representation of the bend pipe weld jig under one embodiment of the present of invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the part-structure sketch map of the bend pipe weld jig under one embodiment of the present of invention, and wherein anchor clamps are fixedly connected through interior bloated plug with helical tube panel.
The specific embodiment
Embodiments of the invention will describe with reference to accompanying drawing.In Figure of description, element or device with similar structures or function will be used the components identical symbolic representation.Accompanying drawing is not to carry out the explanation of exhaustive to the present invention just for the ease of each embodiment of the present invention is described, neither limit scope of the present invention.
Fig. 1 and Fig. 2 show the concrete structure of the bend pipe weld jig under one embodiment of the present of invention.In this embodiment, the bend pipe weld jig comprises: substrate 10 and location-plate 30, location-plate 30 is fixedly connected with substrate 10.Secured in parallel is provided with a plurality of comb plate, comb joints 12 above the substrate 10, and comb plate, comb joint 12 comprises a plurality of deep-slotted chip breakers, is convenient to place the straight-tube portion of tube panel and bend pipe.
Arc stopper slot 34 and gripper shoe 32 are set on the location-plate 30, in this embodiment, hollow out in the middle of the arc stopper slot 34 whole curved strips, location-plate, thus bend pipe 24 therefrom passes.An end of gripper shoe 32 rotatably is fixed on the bottom of location-plate 30, and the straight section of the rotating shaft of end and bend pipe 24 is on the straight line.Arc stopper slot 34 is provided with the securing member 36 that is used for fixing said gripper shoe position.Securing member 36 is worked in coordination, and can move and fixing along arc stopper slot 34.After securing member 36 was fixed, gripper shoe 32 leaned against on the securing member 36, and the sweep of bend pipe 24 rests on the gripper shoe, thereby is fixed.In one embodiment, securing member 36 can be the sub-assembly of screw bolt and nut, those skilled in the art will appreciate that securing member 36 can be other form arbitrarily, so long as the object that can move and be fixed on the stopper slot is all applicable.
As shown in Figure 1; The part pipe 22 of tube panel is arranged on the comb plate, comb joint 12 on the substrate, clamps tube panel and bend pipe substrate with C type folder (scheming not shown), like this; Straight-tube portion with bend pipe 24 is placed on the comb plate, comb joint again; The sweep of bend pipe 24 rests on the gripper shoe 32, and when the straight section of bend pipe was placed on the comb plate, comb joint on the said substrate, the bending section of bend pipe received the support of location-plate upper backup pad.Thereby the technical staff carries out welding procedure to the contact site between tube panel and the bend pipe easily.
In one embodiment, the rotating shaft place of end is provided with a dial, and the angle of said gripper shoe rotation is corresponding with the scale on the said dial.Dial is processed by the 3mm steel plate, on be carved with scale, pointer can be a gripper shoe, also can process separately; The adjustable extent in theory of dial is 0 ° ~ 180 °, and in the present embodiment, the dial adjustable extent is designed to 15 ° ~ 165 °, is enough to satisfy needs of production.
Fig. 3 illustrates the part-structure sketch map of the bend pipe weld jig under an alternative embodiment of the invention, and interior bloated plug 14 is fixedly installed on the substrate, and interior bloated plug 14 is filled in the straight-tube portion of tube panel, and the anchor clamps overall fixed is on tube panel.Straight-tube portion with bend pipe 24 is placed on the comb plate, comb joint again, and the sweep of bend pipe 24 rests on the gripper shoe 32.The interior intensity that expands plug 14 should guarantee to bear to loose to manage and be unlikely to make positioning tool to be shifted and get final product.
In actual use; The technical staff can come to carry out angle orientation to the pipe that looses by designing requirement; After bend pipe is placed on the anchor clamps on request; The straight-tube portion of tube panel is placed on the comb template (the comb template of the tube designs different size of different size), and this moment, anchor clamps were not movable, rotated along straight-tube portion only; The straight length end of bend pipe is by the fixed angle of designing requirement; For example; If it is 45 ° that design angle requires; Be the angle that bend pipe place face and tube panel belong to face, need only utilize dial adjusting angle to 45 °, utilize securing member 36 on the dial to fix behind the dial then bend pipe rested on the gripper shoe to get final product.
Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is limited appended claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite that does not deviate from principle of the present invention and essence, but these changes and modification all fall into protection scope of the present invention.
